Chris,
Thanks! This is exactly what we are doing tonight. And although we have
found a potential fix, we are still scratching our heads as to what caused
this to happen in the first place. Basically, is there anything that
anyone is aware of that would cause disk performance to significantly
change is such a manner that prior to this weekend, all 22 disk were
between 3 and 9% utilized and after the weekend, 6 disk are utilized at
50-70% while the other 16 remained at the normal level?
Thanks,

Chris, I may have stated the information incorrectly. Of the 22 drives, 6 are being utilized at 50-70% while the other 16 are averaging 5%. These disk store nothing but Domino and the entire box runs nothing but Domino. -- Sent from my Blackberry Wireless Device -- Jose L. del Risco Oshkosh Truck Corporation Corporate Domino Administrator (920) 420-5646 Jdelrisco@xxxxxxxxxxxx ----- Original Message ----- From: Chris Whisonant [Chris.Whisonant@xxxxxxxxxxxxx] Sent: 01/25/2007 01:08 PM To: Lotus Domino on the iSeries / AS400 <domino400@xxxxxxxxxxxx> Subject: Re: Domino Utilities and Server Performance Issues Correct me if I'm wrong, but i5/OS doesn't create data like that.

be REALLY curious to see how this person determined that ALL of the

notsure what was the event that concentrated your Domino specific stuff

At first we thought the problem to be a run away process (Routertask on a server was running at 80-90% for about 35min and it wasn'tdoinganything ). Since then ( Monday at 10:35am ), CPU for the entire LPAR
hasbeen averaging 30% and peaking at 65%. Still, as of the time of this email, we are seeing intermittent performance issues. And by that Imean,everything seems to run normally then for some seemingly random
reason,
ittake upwards of 4 minutes just to open an email that does not have an attachment or switch to a different folder view, etc. We sniffed the network and found no network issues occurring during these moments
that
Lotus Notes runs slow. These moments tend to last about 5-10 minutesandall goes back to normal. The performance problems to not seem to tieintoany server task or event taking place. After eliminating CPU we checked Memory. The iSeries guru at our organization informed me that there didn't appear to be any memoryissuesbut did notice that 6 of our disks ( of 22 ) were being hit hard. When
hedid some further digging he noticed that ALL of the data for all 10serverinstances on our LPAR were all on 6 of the 22 disks that we have. This
wasnot the case last week. It would seem that the performance issues
were
related to disk and he is performing a task to evenly distribute thedataamong the 22 disks by usage. Now you are all probably wondering, "How
didall the data end up on just 6 disks when it was spread across 22 last week?"...... That, my friends, is the $100,000 question. If anyone
has
any ideas I would love to hear them. Some background info. Saturday night we applied PTF's to the LPAR. We also ran Fixup on 3 of our server, and Updall -r on 2 of the 3serversthat Fixup was run on. That is the extent of the changes that occurred this weekend. I have
a
directors meeting in the morning at which they will be asking me whyLotusNotes is running slow. I believe I have determined what was the
problem
but not the root cause. If anyone can send me idea before 9am
tomorrow.
Feel free to ask me any questions, I will provide as much detail as Ican.Thanks, Jose del Risco Corporate Domino Administrator Oshkosh Truck Corporation (920) 235.9151 x 2741 Although this e-mail and any attachments are believed to be free of
